Omma stanleyi, copyright David Maddison.

Belongs within: Coleoptera.

The Archostemata are a distinctive group of wood-boring beetles with the labrum fused to the head capsule in adults, and a distinctive wing-tucking mechanism where the wing tips are rolled rather than folded under the elytra (Grimaldi & Engel 2005). The most widespread family in the modern fauna is the Cupedidae, members of which have the the antennal insertions dorsal and more or less approximate, fore coxal cavities separated by a prosternal process, lobed fourth tarsomeres, and grooves on the underside of the thorax for reception of the legs. The Ommatidae of South America and Australia have shorter, laterally inserted antennae, contiguous fore coxal cavities and simple tarsomeres.
